Brief Summary:

A variety of hormones and immune system processes are responsible for how the body responds to illness. This study concentrates on how the hormone cortisol effects the release of immune system factors called cytokines.

Cortisol is a hormone produced in the adrenal glands as a response to stimulation from the pituitary gland. Abnormal levels of cortisol have been seen in several diseases such as depression and multiple sclerosis.

Cytokines are factors produced by certain white blood cells. They act by changing the cells that produce them (autocrine effect), altering other cells close to them (paracrine), and effecting cells throughout the body (endocrine effect). Cytokines are important in controlling inflammation processes.

In this study researchers would like to determine if changes in levels of hormones in the blood are associated with changes in cytokine levels. In addition, researchers would like to learn more about how cytokines respond to hormones in certain diseases.

Detailed Description:
Many of the biochemical alterations observed in people suffering from major depression are changes in the concentrations and activity of components of the generalized stress response. These include the principal hypothalamic stimulus of pituitary-adrenal activation (corticotropin releasing hormone) and the locus ceruleus/norepinephrine system. The current study attempts to provide a clearer picture of the stability of changes during the acute illness, the treatment phase and the recovery process. We particularly wish to determine whether abnormalities in HPA axis perturbability in the well-state can be demonstrated, and if so how these are related to the acutely-ill state, since this information could provide a quantifiable phenotypic marker for depression.
